This inventionrelates to gas heaters of the type known as radiant heaters, and has for its primarf'ly object toimprove the construction and e ciency of heaters of this character. 7

It is another Object of .the invention to embody in a radianttype of gas heater novel and improved means for utilizing to the fullest extent the heat developed by the combustion of the fuel and to control the delivery of the developed heat into surrounding room areas where the heat may be used to the best advantage. I

One form of the present invention is disclosed in the accompanying drawings, wherein: v

3b. Figure 5 is a detail sectional view on the line 5- 5 of Figure 2. V Referring moreparticularly to'the drawings, the numeral 1 designates the metallic base of the heater, the corners'of the heater being provided with vertically arranged legs 2 which are arrangedto engagewith a suitable supporting floor and to hold the heater in spaced relation from the floor, V Arranged within the base is a longitudinally extending gas manifold 3 with which'connect a plurality of burner members 4, the upper portions of which are flanged to engage with the hearth plate 5 of the base. v The base in this instan'ce'is provided with upstanding side walls 6, which are formed with horizontally extending ribs 7 which are adapted to be received within grooves 8 formed in the'sides 9 ofa'clay backing 10. In the preferred ,form of my invention this backing is'of integral formation, and is formed from clay or other suitable ref'ractory material. In addition to the sides'Q" the backing lO-in'cludes a rear wall 11' and an overhanging dome portion 12, the latter being integrally formed with the upper part of the rear wall 11 and with the upper portion of-the side walls9. By this construction the backing provides a radiantreceiv v ing chamber 13. Q 7

Mounted upon each of the burner mem bers 4 and arranged within thechamberl3 are vertically disposed'relatively spaced inner and outer radiant sectionsor elements,

14 and 15 respectively; The inner elements 14 each consist of a tubular clay bodyre- I duced at its lower end to provide a projection 16 which engages with the axial portion of the co operating burner head 4. The I elements 14 are of substantially uniform diameter throughout their length, but their-3 upper'ends are outwardly flared or circular ly enlarged asat 17 in'order'to engage with: v

the inner cylindrical walls 'ofrthe 'outerfl sleeve-like elements 15. These outer elements are also formed from clay vand act as protecting jackets for the inner elements,

in that'the inner elements are completely" received" within said sleeve-like outer -ele-.

ments and supported'in an operating position thereby. ,The outer elements or sleeves are perforated as at 18 to admit of the free escape of the heatdevelopedby the combustion of gases in the annular combus 1 tion spaces formed between the adjacent walls of the elements ll and 15. -This com-v bustion of gases results in highly heating the surfaces 'of'the elements 14: and 15 until the latter obtain a luminous or glowing condition, with the resultthat the heaterdein effect, constitutes a portion or the upper 1 part ofthe; chamber 13, with the exception that the {"chamber 19 is provided with a closed'fforward wall formed-by an outward ly and downwardly projecting lip 20. Ex-

tending longitudinally and centrally of the chamber 19 is a vertically extendlng Web 21, which has its under edge provided with 5 a groove 22, adapted for the reception of the centering projections 23 provided on the upper end of the outer radiant elements 15. The web 21 is provided at intervals with transverse slots 24 which are adapted to receive the projections 23 during the operation of applying or removing the elements 14 and 15 with respect to their operating positions in the heater. The rear wall 11 of the backing is provided with a centrally disposed flue outlet 25, which is disposed contiguous to the upper end of the elements 14 and 15 and communicates with the chamber 19 at the rear side of the Web 21.

Having now described my invention in detail I will now endeavor to point out the more important advantages thereof. In heaters of this character considerable difliculty has been encountered in effectively heating the radiant elements throughout 25 their full height. Under ordinary conditions these elements become highly heated contiguous to their lower portion or adjacent to the burner corresponding to the members 4. This partial heating of the radiant elements is largely due to the fact that the developed heat is allowed to passv too quickly to the flue or stack outlet, or is not properly directed upon the radiant elements throughout their length. In the present invention whole heating of the radiant elements throughout their height is assured by the construction of the dome portion 12 and the provision of the chamber 19 formed therein and the relationship which the surfaces of said chamber bear to the upper portion of the radiant elements. In the operation of the stove the heat developed by the combustion of gases between the elements 14 and 15 passes out wardly and upwardly. A large proportion of this heat; is trapped or confined in the dome chamber 19 and is reflected back from the walls of this chamber upon the upper ortions of the radiant elements, instead of 9 lieing allowed to pass without use to the stack outlet as is the case in customary desifgn. This arrangement provides a very e V cient gas heater of the radiant employing type.

, While I have shown and described the preferred embodiment of my invention, it will be understood that changes may be made in the details of construction without departing from the spirit of the invention or scope of the appended claims.
